Bearing Failure on a Boiler Feed Water Pump

Nowadays, almost all boiler feed pumps must be able to handle both cold starts (high-temperature shock loads) and semi-warm starts without any damage. In these start-up procedures hot feed water abruptly flows into the cold pump, which results in the inner components heating up much faster than the pressure boundary.

Building a Better Boiler Feed Pump | Pumps & Systems

With eight boiler feedwater pumps and 16 glands leaking on average one quart (roughly 1 L) per minute per gland, energy loss was calculated at 124 kW. The plant operates 24 h per day, 365 days per year, causing an annual energy loss of 1,086,240 kWh. These energy savings are purely based on heating requirements and do not include energy costs for water treatment, deaeration, and pumping.
